Established in 1964, the Batley Valve range of designs and sizes is extensive and is probably the most comprehensive of any butterfly valve manufacturer. The standard range of Butterfly Valves has been designed to give cost effective flow control of liquids and gases where a complete tight shut-off is not essential. The ‘swing-through’ vane, which has no contact with the valve body, enables the valves to be used with high pressures and a wide range of temperatures. The standard Butterfly Valve has a basic “equal percentage” characteristic but this is only true between the 10° and 60° open position.
The Batley Range Includes:
Firesafe Hyperseal
Hyperseal
Ledgeseat
Metalseal
Refactory Lined
Spoolseal (Rubber Lined)
Steadseal (Rubber Seal)
Tricentric (Triple offset)
Vulcanised Rubber Lined
As well as Batley we offer Tricentric Triple Offset Butterfly Valves
The triple offset metal seat design of the Tricentric valve provides exceptional performance and dependability over a broad range of demanding applications and service conditions.
Tricentric valves are perfect for cryogenic or high temperature service. They resist wear and are suitable for aggressive media. Valves are available in sizes 75 to 2440mm (3" to 96") in asme pressure class 150 to 600. Tricentric valves are suitable for a wide range of applications in most idustries and offer exceptional value and performance. The compact size and shape combines light weight with the durability of a metal seal and seat. The triple eccentric design eliminates rubbing and wear with bi directional zero leakage. Tricentric is available in standard and exotic materials for the most difficult applications.

The LKB valve is a hygenic, pneumatically or manually actuated flap valve for the installation in high-grade steel of piping systems. HR
The LKB - Row of the high-grade steel valves offers a low flow resistance and a careful promotion of products of low and middle viscosity owing to their large opening range.
The valve LKB is steered either by a control drive or operated manually with a handle. The control drive is available in three versions: feather-closing (type of numerical control), feather-opening (type of NO) and air-to-air one (A/A type) activates. The control drive is in such a way designed that the axial movement of a piston is converted into the rotating motion of a wave around 90°. The torque of the control drive increases, as soon as the valve flap reaches the sealing ring of the flap valve.

General description :
MDC Butterfly valves require only one-quarter turn rotation of the handle to go from fully open to the fully closed position. In the 1- 1/3" Mini Del-Seal™ CF flange series, a spring loaded ball bearing becomes seated in an indent providing a positive mechanical stop. All other size valves employ a roll pin stop method. These quick-acting Butterfly Valves feature an improved sealing action. The opening in the body of the valve has been machined at a slight angle to the plane of the flapper. The flapper is set to rotate slightly off-center. On closure, this causes the sealing pressure to be applied more uniformly all around the O-ring. A reliable, positive seal is made and the tendency of previous designs to roughen the surface of the O-ring and eject it from its groove is eliminated.
MDC Butterfly Valves are low outgassing. All internal surfaces are machined from solid stainless steel bar stock. The handle is made of aluminum. A small O-ring on the stem prevents shaft leakage. The valves are offered with a choice of Del-Seal™ CF ultrahigh vacuum metal-seal flanges or ISO Kwik-Flange™ O-ring seal flanges.
Standard Features :
- Quick open / Quick close with positive locks
- Positive Viton® O-ring vacuum seal
- Type 304 stainless steel valve body
- High conductance
- Choice of Del-Seal™ CF or Kwik-Flange™ KF

Application:
For shut-off, particularly for use with
- liquid
- pasty and
- gaseous, non-abrasive media
Nocado butterfly valves can also be used for shut-off and regulating pourable dry materials.
Special butterfly valves without gaskets can also be produced for these applications.

Dampers - Butterfly Dampers
The Fabricated range of Rotolok Butterfly Dampers are used extensively in the air and dust handling industries generally in fan systems.
They are normally operated remotely by air cylinders, electric or pneumatic actuators although manual versions through the customary hand lever, handwheel and reduction gearboxes can also be accommodated.

1. High Tension Coil Spring
Ensures a stable seal at upper and lower gland even at extreme temperatures or when thermal shock occurs
2. Minimum 3mm PFA Thickness
Seam free PFA injection moulding on the seat and disc to a minimum thickness of 3mm prevents permeation of dangerous fluids or gases
3. No Special Gasket Needed
Stable flange sealing performance is ensured by concentric circular grooves on the flange faces thereby eliminating the need for a special gasket when operating under specified temperatures. The wider sealing area also ensures minimum "creep" at high temperature. Flange sealing mechanism is independent from the seating and gland seals ensuring there is no loss of the line fluid.
4. Total Sealing
Valve structure includes primary, secondary and independent tertiary seal - ie. gland packing. There is also a fourth seal of 0-rings on the top/bottom stems - ie. dust seal.

Based upon model tests, the lens type and lattice door ( through flow ) type valves are optimized and a minimum flow head loss coefficient of 0.07 can be guaranteed.
This type of valve is mainly used as safety valve or as a turbine inlet valve and pump valve. They are operated by oil hydraulic systems for opening and closing or closing weight and hydraulic pressure for opening. For turbine inlet valves oil pressure can be taken also from the governor hydraulic oil system. The sealing system is of flexible adjustable type - rubber/metal or metal/metal. The lattice door type valves can be also equipped with a maintenance seal. The hydraulic and electric / electronic control system is part of the delivery. Auxiliary equipment like bypass, air and vacuum valve, pipe rupture device, connecting pipes are usually in the scope of supply. Water flow through the valve in both directions is principally possible.
